Also maybe look at eventbrite/meetup for events in the future that don't have a venue yet and try to contact them to use your system. Good luck!
You're probably competing with wedding planners (they already have a list of venues!).
Congratulations on your site, it looks clean and professional. I'd add some info (prices are in XX CAD per person, right?). Also to consider, you might want to add a calendar (when you have the availability data), but that can wait - get information on your potential customers first :)
